How the payment is calculated
Total RVU is work plus practice expense plus malpractice, each adjusted by its GPCI factor, then multiplied by the conversion factor. For 40818 in a non-facility setting with national GPCI: (2.76 + 7.8 + 0.35) × $33.4009 ≈ $364.4. The same code in a facility setting pays about $246.5 because facility PE RVU (4.27) replaces office PE RVU.
